West Virginia to Arkansas: master HVAC technician license reciprocity

Arkansas's highest HVAC credential is the HVACR license issued in four classes by the HVACR Licensing Board: Class A (unlimited), Class B (systems up to 25 tons cooling, 1,000,000 BTUH heating or 15 hp refrigeration), Class D (sheet metal ductwork) and Class E (refrigeration); Act 746 of 2025 repealed Class C and moved active Class C licenses to Class B. It is treated here as the master level because Ark. Code §17-33-303(a) issues it to the individual who designs, installs or services HVACR systems, and that person becomes the 'designated license holder' responsible for the work and for registering employees. A new applicant with no licensing background must be 18, show two years of experience as an HVACR contractor or employee (Board-approved education may substitute) through notarized employer affidavits, and pass the open-book class exam administered by Prov ($100, 70% to pass); the annual license fee is $200 for Class A and $150 for B, D and E, with $250,000 liability insurance and eight hours of continuing education per International Mechanical Code cycle. The Board states it has no reciprocal agreements with any other state, but its rules direct it to approve, without examination, apprenticeship, education or training, any applicant holding a license in good standing from a jurisdiction whose HVACR licensing laws are 'substantially similar', meaning one that has adopted a national model mechanical code and uses a comprehensive exam created and proctored by a national examination agency. Under §17-33-104 a state licensee needs no city or county license.

West Virginia does not issue a master HVAC license. The Division of Labor's HVAC Technician license is a single-tier, full-scope credential (see the journeyman level), so a master HVAC mechanic from another state applies for the same HVAC Technician license, with the exam waived under 42CSR34 section 15 or the RECAP Act, and there is no higher personal credential to transfer to. The state-level credential above the technician is the HVAC contractor license from the West Virginia Contractor Licensing Board (W. Va. Code 30-42), required of any person who contracts for HVAC work costing $5,000 or more on residential or $25,000 or more on commercial projects; it is issued to the business entity (including a sole proprietorship) and qualified by a full-time employee or member of responsible management who passes the HVAC classification trade exam and the Contractor Licensing Act (Business and Law) exam, which every applicant must pass. The Contractor Licensing Board waives its HVAC trade exam under reciprocity agreements with Alabama (HVAC classification, effective May 1, 2018), Ohio (HVAC classification including the Business and Law exam, effective May 10, 2018) and Tennessee (HVAC classification, effective December 17, 2020), using a verification form completed by the origin board, and it accepts NASCLA scores and may accept other accredited national exam scores; in every case the workers, including the qualifier if they do the work, must also hold Division of Labor technician licenses, and a licensed HVAC contractor pays no technician license fee. EPA Section 608 certification is a separate federal requirement.
